In the description of the video that you linked to, you wrote: "The signal typically comes up after dark at my location, can be heard for an hour or two, and then slowly fades down to undetectable."
I've been monitoring this new beacon for the past few days and it is exhibiting the exact same schedule and characteristics as how you describe the DRNK beacon in your video, along with transmitting similar "telemetry" data (the most obvious similarity beyond the identifier).
Would it be a safe guess to suggest that the beacon is likely unattended, is dormant as it charges its battery via solar panel during the day, turns on at night via a light sensor, then runs until its battery starts to fade?

In the case of DRNK the lowest battery voltage I remember it presenting was 12.8 or 12.7 (assuming the VB field was battery voltage). If this was a lead-acid battery and VDC the battery should have been still good enough. Also I occasionally, when conditions permitted, would catch it just before sunrise and still hear it on with good battery indications.
I always got the impression it (DRNK) was night time only, dusk to dawn, and that the fading was simply conditions. It typically faded as the band should have been going longer, so my assumption was that the beacon was in a location where at the beginning of the night I had a good path (very little fading, almost ground wave or direct path) but then as the night progressed it skipped over me.
Not really sure how any of that would fit into DNR, even assuming they are related. The values given in your recording for VB and VS are under 5 V. Assuming they are real this would indicate it is not a 12 Volt battery like DRNK presumably was. Of course, that fits. If this is a legal beacon the low power levels required would work just fine on 5 VDC (or even 3 VDC) instead of a heavier and more expensive 12 volt lead acid battery. I said "Assuming they are real" for a reason. If, in your recording, VB is battery voltage and VS is solar voltage, why was the VS still so high (in your second recording) well after sundown anyplace in the contiguous US or Mexico?
